Craftland
FS#1787 - Item Favourite
In the game Terraia you can favorite items so you dont accedently sell/quickstack or dropp them
I would realy like that feature in craftland too and i dont think it is as hard to make because the Mjölnir has also such a behavior.
You could use a command like /favorite slot XY or as it is in Terraia Alt-Leftclick them (not sure if that matches with an excisting shortcut
